''Solanum nelsonii'' (often misspelled ''Solanum nelsoni''〔E.g. Solanaceae Source ()〕), commonly known as Nelson's horsenettle, is an annual to perennial plant in the Solanaceae family, part of the ''Solanum'' or nightshade genus. This poisonous plant is endemic to the Pacific Islands. It grows low to the ground in sandy soil. Nelson's horsenettle was first described by Michel Félix Dunal. The scientific name ''Solanum nelsonii'' has also – invalidly – been given to two other species of nightshade:〔Solanaceae Source ()〕 * ''S. nelsonii'' of Zipp. based on Span. is the ''S. violaceum'' described by Ortega. * ''S. nelsonii'' of Correll is ''S. oxycarpum''. Several varieties of Nelson's Horsenettle have been described, but they are not usually considered valid anymore:〔 * ''Solanum nelsonii'' var.
